Trace fossil or mineralized nodule?

[Kato]

Walking in the hills and chanced upon an exposure of early Devonian here (at least I think it is). 

 

About 3 feet above the rock slab is a 2 foot thick formation bearing either trace fossils or nodules. They seem more like mineralized nodules to me.

 

 

For some reason, yesterday, perhaps due to intense morning light angle on the rock surface, I could just not get a good focus. Note the markings in the brownish trace or nodule. Nothing continuously longer than 4" found. Most exposures either broken or seeming to recede into the formation.

 

 

Thoughts please....

Interesting. 

But can't tell from these photos, I'm afraid.

@Tidgy's Dad well, I meandered back out that way to attempt some better photos. It seems this may be some form of iron oxide mineralization. 

 

 

and another reddish colored one

I agree. 

Mineralogical, certainly some iron minerals present.

@Tidgy's Dad  I think if I wore my spectacles a little more often I would have a higher success rate for photos being in focus and figuring some of these things out on my own faster.
